Electrochemical Honing is a process in which material is removed with help of electrical energy, chemical energy and honing process. For those who don’t know, honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path.In honing a hone tool is used. A…
Fluid is a substance which can flow. Flow of any substance means a contnuous relative motion between different particles of the substance.Both liquids and gases are included in fluids.A gas differ from liquid as the volume of the liquid becomes definite but volume of gas does not remain definite. The main properties of fluids are…
Surface Texture is defined as a degree of finish conveyed to the machinist by a system of symbols devised by a Standards Association. e.g ASA – American Standard Association, BS – British Standards.Surface Texture is the nature of the surface defined by four main characteristics which are Surface roughness, waviness, lay and flaw.Surface Texture is also…
Indexing Mechanism is a mechanism that is used for dividing the periphery of a workpiece into any number of equal parts. The machine used for the indexing mechanism is called indexing head. Indexing head is also known as a dividing head or spiral head.It is a specialized tool that allows a workpiece to be circularly…
A comparator is an instrument that is used to measure precision of a given component by comparing the dimension of a given component with the actual working standard. Pneumatic means air and in pneumatic comparators, the air is used for magnification of measured reading. Pneumatic comparator work on the principle that if an air jet…
Comparator is a device that is used to measure the roughness of the surface. It is a precision measuring instrument in the metrological field.Sigma comparator was developed by a company named Sigma Instrument Company, USA. It is mechanical comparator in which magnification ranges from 300 to 5000.This comparator does not require any power supply. Parts…
Air lift pump is a device that is used to lift water from a well or a sump with the use of compressed air. This pump is also called a mammoth pump.Airlift pumps have been used since the beginning of the 20th century.The first airlift pump was invented by the German Engineer Carl Emanuel Loscher in…
Vane Compressor is also known as Rotary Vane Compressor or Sliding Vane compressor.Vane Compressor was invented by Charles C. Barnes of Canada. He patented it on 16 June 1874.Vane Compressor are one of the most widely used products in today’s world. They serve a wide range of industries.Vane Compressor used centrifugal motion to generate compressed air. Vane compressors…
Solex carburetor is a modification of simple carburetor. The simple carburetor works well in normal working conditions but it does not work well in conditions like winter and summer season, idle condition and high acceleration condition. In these conditions, Solex carburetor works well.The main work of carburetor is to create air-fuel mixture in the right…
Capstan Lathe is the modified form of Engine Lathe and Center Lathe in which the tailstock is replaced by a hexagonal turret tool head. It was first developed by Pratt and Whitney in America in 1860. It was needed to develop capstan lathe because in center lathe there was only one tool post and only…
